Hm...I don't think I've said it before, so I will now:
There's a big motorcycle board I'm on which recently suffered an exodus. It was a rowdy place where most anything was okay. But the site owner, due to the large amount of grab assing turned asshattery, started to get phone calls and people showing up at his front door bitching about other people grab assing with them. Drama on steroids.
So they clamped down on the rules to make the place a little more civil. Of course, all the fucking funny people left and started their own board. Invite only.
What they didn't do at the new board was put a strong ban hammer in place, and it's apparent to me that all that really happened is the shit stirring moved from one place to another. Also, because there's no back door, and anyone there can invite anyone they want, the place is growing like a weed ... I think it's doomed to recreate an old pattern.
It's not fun to think of the need for a wide open back door, but I swear, it's what makes this place so clean and noise free.
Sure, some innocents get popped in the head from time to time ... such is the price of freedom.
